摘　　要：动态导航技术可以准确地对钙化根管进行定位和疏通,避免牙本质的过度去除并降低了并发症的概率。目前动态导航在非手术牙体治疗中最常用的配准方式为U型管配准,然而此法存在二次就位误差、需要额外拍摄配准用锥形束计算机断层扫描(cone beam CT,CBCT)影像等缺点。本病例采用数字化口内扫描辅助配准,动态导航下成功定位并疏通下颌前牙钙化根管,证明了数字化口内扫描技术应用于动态导航配准的可行性。Dynamic navigation technology allows accurate localization and negotiation of calcified root canals,avoiding excessive dentin removal and reducing the probability of complications.Currently,the most common registration method for non-surgical endodontic treatment in dynamic navigation is U-shaped tube registration,which has disadvantages of secondary seating errors and the need to take additional cone beam CT(CBCT)scanning for registration.In this case,intraoral scan-assisted marker registration was used for dynamic navigation and the calcified root canal of the mandibular anterior teeth was successfully localized and negotiated,which demonstrated the feasibility of digital intraoral scanning technology applied to dynamic navigation registration.
